Bob,
No problems with cleaning by standard rug techniques.
Thorough pre-vac on both sides, can be hung and beaten if high dust-load.
Mist-spray with Woolsafe micro-splitter and brush in with Host machine fitted with gold (soft) brushes.
Extract a 65C with plain water or acidic rinse agent if required due to previous clean. Use suitable 3" rug tool rather than 12" wand and if possible take outside and 'flick-shake' to normalise (long) pile prior to quick-drying with air mover.
